Issue #292790 by ag888, kjay, mr.baileys, recidive, malc0mn, jonathan1055, null: fix menu machine name validation form API constuct, so we don't need to validate it with custom code

#682784 by andrewfn, naxoc, Island Usurper: make it possible to remove query strings and fragments from menu items after added

#317775 by Starminder, pwolanin: do not store the menu router table serialized in cache, since it cases more performance problems then it solves

#326210 by AlexisWilke, grendzy, jhedstrom: Take the menu item in its first submission and menu_nodeapi() by reference, so that any modifications of the item in the saving process will carry over to other submit handlers; making itpossible to write modules extending menu item manipulation

#328110 by marcingy, swentel, Damien Tournoud, pwolanin, David_Rothstein: the link argument is passed by reference to menu_link_save(), so avoid overwriting local variables in menu_enable().

#220004 by webernet: menu ordering weight region was not wide enough (like on the menu reordering screen)

#216904 by theborg, pwolanin: items were not properly ordered in tabledrag.js when more then the number of possible values

#215858 by pwolanin: localized menu options were saved into the database, avoid this by using different variable names / array keys

#216014 report by meba, patch by myself: menu_install() did not use get_t() for its menu item creation

#208498 by pwolanin: remove pager from menu admin page (for big menus, you will need to use a contrib module)

#195091 by Rowanw: (usability) swap enabled and expanded checkbox in menu admin and allow setting elements without children to be expanded

#205843 report by asimmonds, patch by chx: menu_valid_path() was used as an API function, but was located in menu.module, move to menu.inc

#202425 by keith.smith: standardize reference to block placement page as 'blocks administration page' to avoid any confusion

#200069 by keith.smith: new standard for 'more information' links in module help texts, as the handbook we referred to before was renamed

#195083 by Rowanw and keith.smith: menu items are not displayed on the main menu page anymore; update help text

#199191 by Nick Lewis, Lynn: (usability) include the enabled checkbox directly on the menu item editing page too

#196043 by chx: menu items saved in the update but broken on the new system (due to coming from disabled or old modules) were not possible to delete

#197385 by chx and catch: the menu system stores only non-aliased paths, so alert users to this, when they try to save aliased paths

- Patch #163246 by keith smith, freso, O Govinda, catch, webchick et al: fixed minor spelling issues and fixed spacing issues.

#194166 rollback and additional comments by chx: developers can modify menu editing behavior with hook_form_alter(), no need for menu API hacks, which were half done anyway

- Modified patch #194166 by profix898 and chx: menu system does not respect MENU_MODIFIABLE_BY_ADMIN.

#194174 by webernet: flag DnD modified links as customized, so they can be restored to their original form on the UI

#191360 by chx: allow contributed modules to override the book and menu parent selectors (to improve usability and performance)
